FLUID ROUTING METHODS FOR A SPIRAL HEAT EXCHANGER WITH LATTICE CROSS SECTION MADE VIA ADDITIVE MANUFACTURING

摘要

A spiral heat exchanger features: a cold fluid inlet manifold, a hot fluidinlet manifold and at least one spiral fluidpathway. The cold fluid inlet manifold receives cold fluid and provide coldinlet manifold fluid. The hot fluid inlet manifold receives hotfluid and provide hot inlet manifold fluid. The at least one spiral fluidpathway includes cold spiral pathways configured to receive thecold inlet manifold fluid and provide cold spiral fluid pathway fluid, and hotspiral pathways configured to receive the hot inlet manifoldfluid and provide hot spiral fluid pathway fluid. The cold spiral pathways andthe hot spiral pathways are configured in relation to oneanother to exchange heat between the cold spiral pathway fluid and the hotspiral pathway fluid so that the hot spiral fluid pathwayfluid warms the cold spiral fluid pathway fluid, and vice versa.
